Hey, thanks for the report and the screenshot. I can see the inline trace bar showing up in the reply.

This is a known bug. Sometimes Composer 2.5 mixes internal thinking and editing tokens into the visible reply text instead of keeping them in a separate thinking block. We’ve logged the issue, but I can’t share an exact fix timeline yet.

You’re not the only one seeing this. Here are a couple threads with the same symptom if you want to follow along:

As a temporary workaround, if it’s getting in the way, you can switch to a different model in chat. I’ll post here once we have an update on the fix.
